Battery charger modules
* GV3 and GV4 panels require a D1640 transformer. For legacy products refer to the control
panel documentation.
** The D8132 can support up to 27 Ah of backup battery. If two batteries are used they must
have the same Ampere-hour (Ah) rating.
Two cables are provided with the module for connections to the control panel and additional
batteries.

Wiring for standalone power supply
The D8132 module can operate as a 12 V standalone power supply. Standalone operation
does not have battery supervision or load shed, and therefore is not recommended for critical
loads requiring supervision.
